The XM800 Armored Reconnaissance Scout Vehicle (ARSV) was an experimental scout vehicle developed by the US Army in the 1970s. It was part of a series of armored vehicles being designed by the Army to replace their existing armored personnel carriers, the M113 and M114, with vehicles with greatly improved fighting capabilities. While the MICV-65 program focused on troop carriers, a separate requirement for a scout vehicle led to the XM800. None of the vehicles from the MICV-65 project entered production, although they provided valuable experience that was used in the M2 Bradley.

In 1965, Australia, Canada, the United Kingdom and the U.S. began to collaborate on a common reconnaissance vehicle. The effort came to nothing as the UK developed the Combat Vehicle Reconnaissance (Tracked) Canada acquired the Lynx. The U.S. Army issued a request for proposals for the Armored Reconnaissance Scout Vehicle as a replacement for the M114 in October 1971.^[1] Six companies responded: Chrysler, FMC Corporation and Teledyne Continental (with a variant of the Scorpion) submitted tracked designs while CONDEC, Ford and Lockheed Missiles and Space Company submitted wheeled designs.^[1]^[2]

Two different vehicle designs were selected for further evaluation in the XM800 program. Lockheed's XM800W unconventional articulated 6 × 6 wheeled armored car and FMC's XM800T tracked version.^[1] The contenders produced four prototypes each (three of which were delivered to the Army and one was retained by the company), test rigs and a hull for ballistics testing.^[1] Both models initially featured the same turret with the US-built version of the Hispano-Suiza HS.820 20 mm autocannon, the M139, as the primary weapon, as well as an M60-derived machine gun on a pintle mount. The M139 had been selected for all of the MICV projects. The XM800W was based on Lockheed's work with the 8 × 8 Lockheed XM808 Twister which was trialed in Vietnam.^[3] The XM800W was later equipped with a new turret design that kept the M139 cannon, but that had an upper cover that flipped forward to form a gun shield, or rearward to close up.^{[ citation needed ]}

During the June to August 1974 force development test and evaluation, the XM800T and XM800W were evaluated with and without their turrets. They were compared with vehicles including the M113A1 armored personnel carrier (utilized as a baseline), M113A1 AIFV, Canadian Lynx, PI M113A1 1/2 featuring a turbocharged engine and tube-over-bar suspension, British Scimitar reconnaissance vehicle, modified M551 Sheridan, XR-311 dune buggy, and V-150 armored car.^[2]

The test report determined that the XM800T displayed superior overall performance as an ARSV compared to both the M113A1 and the XM800W. Conversely, the XM800W exhibited commendable performance on roads with its quiet operation and high speed. Nevertheless, its limited cross-country mobility, along with issues of lateral instability and directional control, made it inferior overall compared to the M113A1.^[2]

As of 1976, the program was reported to be in trouble. Jane's Christopher F Foss reported that while FMC's vehicle appeared to be superior, neither vehicle had the required surveillance equipment, anti-aircraft armament, and could not operate for a continuous 24-hour period. As of early 1974, $39.5 million had been spent on the program.^[1]

An infantry fighting vehicle (IFV), also known as a mechanized infantry combat vehicle (MICV), is a type of armoured fighting vehicle used to carry infantry into battle and provide direct-fire support. The 1990 Treaty on Conventional Armed Forces in Europe defines an infantry fighting vehicle as "an armoured combat vehicle which is designed and equipped primarily to transport a combat infantry squad, and which is armed with an integral or organic cannon of at least 20 millimeters calibre and sometimes an antitank missile launcher". IFVs often serve both as the principal weapons system and as the mode of transport for a mechanized infantry unit.

The Bradley Fighting Vehicle (BFV) is a tracked armored fighting vehicle of the United States developed by FMC Corporation and now manufactured by BAE Systems Land & Armaments, formerly United Defense. The BFV is named for U.S. General Omar Bradley.

The M113 is a fully tracked armored personnel carrier (APC) that was developed and produced by the FMC Corporation. The M113 was sent to United States Army Europe in 1961 to replace the mechanized infantry's M59 APCs. The M113 was first used in combat in April 1962 after the United States provided the South Vietnamese army (ARVN) with heavy weaponry such as the M113, under the Military Assistance Command, Vietnam (MACV) program. Eventually, the M113 was the most widely used armored vehicle of the U.S. Army in the Vietnam War and was used to break through heavy thickets in the midst of the jungle to attack and overrun enemy positions. It was largely known as an "APC" or an "ACAV" by the allied forces.

The Combat Vehicle Reconnaissance (Tracked), abbreviated CVR(T), is a family of armoured fighting vehicles (AFVs) developed in the 1960s and is in service with the British Army and others throughout the world. They are small, highly mobile, air-transportable armoured vehicles, originally designed to replace the Alvis Saladin armoured car.

The FV101 Scorpion is a British armoured reconnaissance vehicle, and also a light tank. It was the lead vehicle and the fire support type in the Combat Vehicle Reconnaissance (Tracked), CVR(T), family of seven armoured vehicles. Manufactured by Alvis, it was introduced into service with the British Army in 1973 and was withdrawn in 1994. More than 3,000 were produced and used as a reconnaissance vehicle or a light tank.

A huge number of M113 Armored Personnel Carrier variants have been created, ranging from infantry carriers to nuclear missile carriers. The M113 armored personnel carrier has become one of the most prolific armored vehicles of the second half of the 20th century, and continues to serve with armies around the world in many roles.

The Spähpanzer Luchs is a German 8x8 amphibious reconnaissance armoured fighting vehicle (Spähpanzer) that was in service from 1975 to 2009 with the German Army, who used 408 in their armoured reconnaissance battalions. It was developed by Daimler-Benz between 1968 and 1975, replacing the M41 and the Schützenpanzer SPz 11-2 Kurz.

MICV-65, short for Mechanized Infantry Combat Vehicle, 1965, was a US Army project that studied a number of armored fighting vehicles that would replace the M113 and M114 as well as take on a variety of new roles. A number of designs were studied as part of the MICV project, but none of them entered service for a variety of reasons. Nevertheless, experience gained in the MICV project eventually led to the M2 Bradley, which incorporates many of the MICV concepts.

The Expeditionary Tank was a light tank developed in the 1980s initially by Teledyne Vehicle Systems. Later joined by General Dynamics Land Systems (GDLS), the companies entered the US Army's Armored Gun System (AGS) competition with the design. Since the tank never entered service, it did not receive an official designation. Alternative names for the Expeditionary Tank include the Teledyne Light Tank and the Slammer.

The Lynx is a German armoured fighting vehicle developed by Rheinmetall Landsysteme. The Lynx, configured as a KF31 infantry fighting vehicle (IFV), was unveiled at the Eurosatory defence exhibition on 14 June 2016. The KF41 variant was unveiled at the Eurosatory defence exhibition on 12 June 2018. According to Rheinmetall, the Lynx family of tracked armoured vehicles is at the forefront of a new trend in IFV design toward armoured vehicles with lower unit and through-life costs and reduced complexity. One of the key principles of the Lynx concept is the integration of proven sub-systems with a high technology readiness level to reduce development time, cost and technical risk.

The M113 armoured personnel carriers are American produced military vehicles that have operated in the Australian Army since 1964. An initial pair of M113s was purchased for trials purposes in 1962. Either 817 or 840 were acquired by 1979, comprising nine different variants. A long-running modernisation program that commenced in the 1990s resulted in 431 M113s being upgraded between 2007 and 2012. All of the upgraded M113s remain in service as of 2020.
